Well although the amount of hot water is slight, and there's much more cold water, I would assume that the water would more than likely increase in temperature.... even though it may be slight
A mutation is known to be a natural process in which the DNA sequence is changed in a living organism. Genetic variation is the change in both alleles and genes. Both throughout and amongst the pop.
2Al + Fe2O3 ——-> Al2O3 + 2Fe
This is a single displacement reaction
A sample of crude sodium iodide was analyzed by the following balanced reaction. The oxidation number of S in SO₄²⁻ is +6.
8 I⁻ + 6 H₂O + SO₄²⁻ → 4 I₂ + H₂S + 10 OH⁻
Let's consider the following unbalanced redox reaction.
I⁻ + SO₄²⁻ → I₂ + H₂S
- The oxidation number of I goes from -1 (I⁻) to 0 (I₂) so it is oxidized.
- The oxidation number of S goes from +6 (SO₄²⁻) to -2 (H₂S) so it is reduced.
The corresponding half-reactions are:
I⁻ → I₂
SO₄²⁻ → H₂S
We will perform the mass balance adding OH⁻ and H₂O where appropriate.
2 I⁻ → I₂
6 H₂O + SO₄²⁻ → H₂S + 10 OH⁻
Then, we will perform the charge balance adding electrons where appropriate.
2 I⁻ → I₂ + 2 e⁻
8 e⁻ + 6 H₂O + SO₄²⁻ → H₂S + 10 OH⁻
Finally, we will multiply the first half-reaction by 4 and the second by 1, and add them.
4 × (2 I⁻ → I₂ + 2 e⁻)
1 × (8 e⁻ + 6 H₂O + SO₄²⁻ → H₂S + 10 OH⁻)

I believe the correct answer is the fourth option. A molecule refers to two or more atoms held together by covalent bonds. These atoms could be the same element or different elements. The bonding of the atoms would result to a neutral charge or a charge of zero. Examples are O2, H2O, HCl.
